Application filed March 29, 1917. Serial No. 158,421.

To all whom it may concern:

Be it known that I, FREDERICK W. Mrt'- 'rnnnenn a citizen of the United States, residing at Addieville, in the countyof Washington and State of Illinois, have invented certain new and nseful Improvements in @raining-Tools, of which the following is a specification.

This invention relates to graining tools having fer its object the provision of a simplified manually operable tool which will be effectual in its operation and which per mits expeditious removal and replacement of the graining roller7 when desired.' l.

Another object-is to utilize aV roller carrying frame which can be conveniently supportedand guidedby one hand of the operator, permitting the operator to use his other hand for rotating the graining roller, the frame being equipped with a yielding side to facilitate removal of the roller.

The above and other objects and advantages of this invention will be in part described, and in part understood from the following description of the present preferred embodiment, the same being illustrated in the accompanying drawings in which,

Figure 1 is a side elevational view of a tool constructed in accordanceI with my invention, parts thereof being broken away.

Fig. 2 is a top plan view of the same, and

Fig. 3 is a detail fragmentaryT end clevational view of the device.

In the drawings, a frame generally designated 1 is provided, which may be made of wood, metal or any other suitable material and comprises a head 2 and a handle 3. The head 2 is equipped with an upstanding integrally formed side piece 3 which has a wear plate Al mounted on its outer face. A yielding side strip 5 is mounted on the head 2, being secured to the end opposite the end upon which the side piece 3 is formed. 1t will be noted that the side strip 5 consists of a metallic strap, one end 6 of which is flexed into snug engagement with the lower margin of the head 2 and fixedlv secured thereto in any suitable manner. The strap extends around the end of the head 2 and is normally retained in snug engagement therewith by a locking member 7. The inherent elasticity of the strip 5 will cause the latter to normally flex outwardly from the end of the head 2 as soon as the member 7 has been released. However movement of said strip is limited in view of an abutment 8, the latter in this instance comprising a headed stud, the shank of which is passed thronghthe strip and into the head 2 of the frame. The locking member 7 consists of a bar, one end of which, as indicated at 9, is pivotally mounted on the upper margin of the head 2 of the frame. The opposite end of said locking member extends beyond the end of said head 2 and is provided with a recess 9 which receives the strip 5.

A driven shaft 10 is journaled through the side member 3 of the frame 1 and has the Vinner end thereof mounted in a corresponding recess formed in one end of a graining roller 11. A pintle 12 is mounted in the opposite end of said roller and is adapted for engagement in a complemental opening formed adjacent the top of the strip 5. It will therefore be appreciated that rotation of the driven shaft 10 will impart movement to the roller 11. The roller 11 is preferably made of a resilient material and is equipped on its periphery with suitable graining impressions as indicated in Figs. 1 and 2, which impressions will be transferred to a surface when the roller is passed over the latter. It will be noted that a cross piece is arranged through the driven shaft in order to limit inward movement of the roller on said shaft whereby contact of the latter with the side p-iece 3 is prevented.

A shaft 12 is rotatably mounted in suitable bearings formed on the wear plate Il and has the shank thereof, between the bearings formed to provide a worm 13, the latter meshing with a pinion 14C which is carried by the driven shaft 10. The shaft 12 carries a cog wheel 15 which is adapted to mesh with a master wheel 16, the latter being rotatably mounted on the side of the frame head 2. Motion is imparted to the master wheel 16 by a suitable hand crank 17 which is preferably integrally formed on said wheel.

ln operation therefore, it will be appreciated that. the handle 3 is to be grasped by one hand of the operator and the roller 11 thereby forced into engagement with the surface which is to be grained. The other hand of the operator can be used for rotating the master wheel 16 through the medium of which motion is imparted to the cog wheel 15, through the worm 13 and ultimately to the driven .shaft 10, through the pinion 14. When itis desired to replace the roller l1 the locking member 7 is moved on It will be understood that the above de` scription and accompanying drawings comprehend only the general and preferred embodiment ,of my invention and that various minor changes in details of construction, proportion and arrangement ot' parts may be made Within the scope of the appended claims without sacrificing any of the advantages of my invention.

Having thus fully described my invention, what l claim as new aud desire to secure by Letters Patent is :u

l. A graining tool including an integral 'frame and handle, the former being equipped with a revoluble graining roller, a gear Wheel rotatably mounted on the :trame adjacent said handle and having its periphery movable in the plane above the latter, an

operating member formed on the gear Wheel and extending beyond its periphery, and a gear mechanism inV mesh'yvith said gear Wheel and operatively connected With the graining roller for imparting movement thereto When the operating member is moved.

2. A graining roller including an integral frame and handle having an upstanding side piece, a resilientzstr-ip secured to the iframe adjacent the handle and 'flexed around the side of the-frame to lie parallel with said upstanding side piece, a grainmg roller rev- 'olubly mounted between said parallel side members, means mountedY on the upper margin of said frame and extending laterally therefrom into engagement: with the resili ent si de piece substantially as set forth.

In testimony whereof I atliX my signature in presence of two Witnesses.
